CAR-TRUCK;

Application Sled September To all whom 'it muy concern:

Beit knownthat I,JouN (..BARBER, e. citizen of the United' States,residing at Chicago, in the county oi' Cook and State of Illinois,

have invented certain new and useful Inif proveme'nts in Car-Trucks; andldo lierebv declare the following exact-description of will enableothers skilled in the art to which it appertains to make and nsethcsame.

My invention relates to car trucks of the general type disclosed inmynumerous prior patents, wherein provision is made for a limited lateralmotionof the car body relative to the truck, in addition to thecustomary swiveling motion ot' said parts, and wherein both the lateraland the radial motions are taken on :ulti-friction rollers.

More specifically stated, my present invention relates to a cur truckadapted to support the car body and its load through the side bearings,with provision for both the late-ral and swiveling motions, on the Samegeneral principle disclosed in my prior patent 853,012, of du'te August1.3, 1907; and my present invention has for its object to provide a cart'ruclV having cast steel girder side frames :md coperating partsadapted advantageously to all'ord the said lateral and radial'motions,with the car body rand its load so carried eari Us Tontiis end, myinvention consists of the novel devices and combinations of deviceshereinafter described.

My improved truck is illustnated in the accompanying drawings, whereinlike notations refer to like parts throughout the several views.

In said drawings: Figure l is a view in side elevation, with some partsshown in section, some parts removed, and the position of other partsrepresented in diagram only. Fig. 2 is a plan view of the parts shown inF ig. 1, With` the car body bohter removed, some parts being brokenaway. F ig. 3 is a detail in section, on the line fc3 rc3 of Fig. 1,with the body bolster removed and some parts broken away. Fig. 4 is adetail showing one of the lower members of the lateral motion bearingplates, in side elevation as in 1, and the underlying or supporting srings and spring caps in section, with the p ate and spring capsseparated from each other. Fig. 5 is a View chieti in vertical crosssection through the truc but partly Specication of Letters Patent.

l in end elevation, with somo portions bf; ken f away. Fig. 6 is a viewol" some of the parts i shown in Fig. 5 chiefly in plan but partly in ,lhorizontal section, on the line r" 1; of Fig. Fig. T is a plan view ot'one of the girder side l frame castings, with some ot' the parts sup- Iported there y removed therefrom. Fig. 8 a detail in vertical section ontnelin.n :138:58 l of Fig. 6,- and Fig. i) is a '.letail in plan viewshowing part of a gif'der' frame with slightly modified form of thebolster column lugs. l Referring to Fig. 1, the diagram lines 1 irepresent the positlons of the Wheels of a car truck.

The numeral 2 represents one of the botl tom tie bars andthe numeral 3represents one l ot' the cast steel girder-type side frames. l This sideframe casting 3 has cast integral Ii therewith spring supportingbrackets, with one set thereof projecting outward lroin 'the Ilmainvertical web of the casting, marked l with the numeral 4t, and the otherset thereof projecting inward from the inner face of the said web andmarked with the numeral 5, this inner set 5 being integral with eachother and having its opposite end portions depressed relative to itscentral or raised portion. The outer braci-:ets 4 serve simply as springsupports or base plates, and are of pocketlikc form to retain the lowerends of the v springs 6 in proper working position. The l inner or onepiece bracket .5 has a double l function, serving as a means forconnecting ,l the ends of theI double cross tie 8 to the side l frame insuch a way es to bring theI ends of ,l the cross ties on thev same levelas the raised portion of the bracket, and then cooperating ,l with theseparts to support the inner pair of the springs 6. The cross ties 8 arebent tol ward each other so as to meet at their central i portions, andare there connected together y binding plate 9 riveted or otherwiserigidly secured to the horizontal webs of the angle bars out of whichthe cross ties 8 are made, all as clearly shown in Figs. 5, 6 and 7. 5The double brackets 5 have end flanges and l the ends of the doublecross ties 8 are riveted, l both to the horizontal and the vertical Websor Hang-es of the said brackets 5. W'ith the I cross ties 8 thus securedto the inwardly proj ecting brackets 5 of the op y osite or an* of sideframe castings 3, it is, o coursel o vious that the said side frames arerigidly connected thereby. The shape to which the said ,i cross tics 8are bcntmake the same, when united by the binding plate 9, constitute anX-shape cross tie which is best ada ted to afford the greatest strengthand tlie best distribution of the strains which must be taken thereby.The vertical rivets con- 5 necting the horizontal webs of the ends ofthe cross ties 8 with the brackets 5 serve to center the lower ends ofthe innerv sets of springs 6 which rest on the ends of said cross tiesand the raised ror central portions of said 10 brackets 5, as best shownin Figs. 5 and 6.

- It will be seen that the springs 6 are thus located in two sets onopposite sides of the central vertical 'eb of the girder casting 3. Onthe springs 6 are mounted separate spring caps 10 with centering lugs ontheir upper faces.

The numerals 11 represent the lower mem bers of the lateral motion.-roller bearing plates, and are so constructed as to afford downwardlyTprojecting legs which straddle the top girders or flanges of the sideframe castings 3; and because of this fact may hereinafter, for brevity,be called the straddlers or straddling plates. The depending legs of thesaid straddlers 11 rest on the spring caps 10, one leg resting on theouter pair of spring caps and the other on the inner pair of springcaps, and these legs being provided with notches which register with theraised centering lugs of the caps, as

clearly shown in Figs. 4 and 5. The strad dlers 11 are' mounted withfreedom for vertical motion, in respect to the side frame castings 3,under the s ring action, but are held against any latera motion; and forthis urpose the straddling legs are embraced by ugs 12'of hook-like formprojecting from the top girder or flange of the casting 3, as best shownin Figs'. 1, 5 and 7, so that the legs of 40 the said plates 1 1 workbetween the said lugs 12 an'd the top girder of the casting 3, and arethereby guided and held for straight line vertical action, and preventedfrom` any lateral motion or forward and backward motion on the saidcastings 3. On the faces or bearing surfaces of the said lates 11 are`mounted the lateral motion ro ers ,13. On

these rollers 13 rest the top members 14- of the lateral motion bearingplates.

14 are riveted or otherwise secured to the under surface of the truckbolster 15, at the o posite ends of the bolster, or directly over t elower bearing plates or straddlers 11, as

. best shown in Figs. 1 and 5.t

is conveniently made of a simple channel bar,

and the upper bearing plates 14 are riveted to the under surface of thehorizontal web of the channel, the channel being applied with this webuppermost, as shown. To the upper surfacepf the bolster 15, at itsopposite ends, are riveted or otherwise rigidly secured the bottommembers 16 of the side bearing plates, and on'these rest the side bearinrollers 17 disposed crosswise of the latera motion rollers 13, on radiallines intersecting These plates The bolster 15 the center of the truck,as best shown in Fi s. 2 and 5. On the side or radial motion rol ers 17rest the top members 18 of the side bearings, these being riveted orotherwispl rigidly secured to the ends of the car body bolster 19. Theseside bearing plates 16 and 18 are of the proper shape, on their bearingsurfaces, to afford treads for the rollers 17, which will permit thelatter to travel in the arc of acircle struck from the center of thetruck, as clearly shown in Fig. 2. The truck bolster 15 is provided withstop lug chafing lates 2O which work between bolster guide ugs 21 or21arising from and rigidly secured to the top girder of the side frame .80castings 3. These bolster guide lugs may be cast integral with the saidcastings 3, as those shown in the main views and marked with the numeral21, or they may be separately cast and be riveted or bolted to the saidcastings 3, as in the slight modification illustrated in Fig. 9. Thestop lugs of the chafing plates 2,0 are properly spaced to permit duelateral motion of the truck bolster 15 and to limit the same by comingin con- 90 tact with the sides of said bolster lugs 21; and, of course,the said lugs 21 serve to guide the bolster in its up and down motionand to take the forward and backward thrusts therefrom.

The truck and body bolsters are connected for the customary swivelingmotion, on th`e cross center of the truck, by center or swivel platemembers 22 and 23, which telescope with each other, with the lower plate22 rigidly secured to the truck bolster 15 and the upper member 23rigidly secured to the body bolster 19, and the two separably connectedby a nutted king bolt 24, as clearly shown in Fig. 5. It should be notedthat these plates 22 and 23 do not sustain any part of the load, butserve simply to afford the swiveling connection between the car truckand the car body. The load is carried entirely through the side bearingsand directly over the vertical web of the side frame castings 3 `on thesprings 6, with freedom-for the customary yielding or spring cushionedmotion, in a vertical direction, freedom -for a limited lateral motiononthe rollers 13, and ,with i'i freedom for the required radial motionon the side bearing rollers 18. The load is therefore carried in themost advantageous manner, for the best distribution of the strainstherefrom on the truck, while, at' the 120 same time, keeping the wellrecognized advantage of the radial and lateral motions on rollers,reducing the friction and the wear and tear on the wheel iianges and therails, in rounding curves.

As a detail, to prevent loss of the rollers`13 or of thestraddlers 11,in case of derailment,

lthe said plates 11 are connected to the y truck bolster 15 by nuttedbolts 25 carried by the bolster'andworking in laterally elon- 130 castintegral therewith @ties 8 affords vthe re emacs .gated slots 26 of theplates 11, as best shown in F ig. 5. The bolt is of such length and soapplied as to afford a loose connection between the said connectedparte, permitting lthe bolster to rise slightly relative to theunderlying bearing plate 11, under the lateral travel of the -rdllers 13to the higherparts of their bearing .surfaces on theo posing faces ofthe plates 11 and 14; and tie slots 26 intheplates 1 1 must be of therequisite length to permit ne limited lateral travel of the bolsterV 15relative to the plates 11. The .bearing surfaces of the plates 11 and14, on which the lateral motion rollers 13 travel, aire ot the kinddisclosed and claimed in prior patent 784,096,` granted to Lee W.Barberg, b

of date March 1905, andA have all the advantages therein noted. As afurther detail, it will be' seen, by reference to Figs. 2

and 5,. that the side frame castings 3 have socket lugs 27, in .pro erpositions to support bearings 28 for ra e hangers 29. The X-shape of thecross uisite clearance for the support of the bra e beam (not shown),from these bearings 28 and hangers 29.

lIn addition to the advantages .already noted, as resulting from the wayin which the load is Ycarried on this truck, it should be further noted'that the parts required for properly mounting the springs, the bolsterand the anti-friction devices, do not any wise weaken the side frames orgirder castings 3, but some thereof, such as the projecting brackets 4and 5 and the bolster 2.1, considerably strengthen said main castlings3.

Comparing with my prior patent 863,012, of August 13, 1907, it should benoted that in my said prior patent, the truck bolster v thereindisclosed has no lateral motion; but

simply has a vertical motion, and itself carries the bottom members ofthe lateral motion roller bearing plates, on which the rollers traveland which support the so-called floating platevl eral motion and theside motion rollers. The same remarks a ply in substance to the Lake andDevere l patent 7 98,350, of Aug11st 29, 1905, referred to in my patent863,012. Otherwise stated, the Lake and Deverell truck bolster has nolateral motion:

So far as l know, my present design l1erein disclosed, is the firstwherein the load is carried through the side bearing rollers and lateralmotion rollers directly from the side ames, and wherein the truckbolster is free for lateral motion. This is an improvement in manyrespects. 'lh-c two holsters always travel together in. the lateralmotion.y and hence the two swivel or turn :ingoia-rij.; in respect toeach other, on a uniform or constant center in the radial motion; enfrelation of the said parte citons' a ,er reliable and stabledistribution o; the #trains 7 located between the lat `said side frames,

tion rollers and bearing flint ,i

from the load. Incidentally, this improvement makes it unnecessary tohave any elongated slot, 4in either -of the telescoping center platesfor the king pin. stated, the swiveling connections can be made muchcloser, more stable and reliable.

What I claim is:

1. In a car truck, the combination with truck and body holstersconnected for swiveling motion in respect to each other, of lateralmotion and radial motion auti-ric tion. bearings supporting the ear bodyand its load directly from the side frames, with freedom for the lateralmotion of said truck bolster on said lateral motion anti-friction eariUs and freedom for the radial motion of said`J body bolster on saidradial motion anti-friction scribed.

2. In a car truck, the combination with side frames, of truck and bodyholsters c onbearings, A'substantially as de- Anected for swivelingmotion in respect to each other, bolster supporting springs on lateralmotion bearingy rollers and bearing plates for said truck bolster, withthe lower members of said lates resting on the caps of said springs anheld by said frames with froedom'for vertical motion only, and radialmotion rollers and bearing plates for said body bolster, vwith theOtherwise lower members of said plates fixed to the truck bolsterdirectly over the top members ofthe lateral motion bearing plates,whereby the car body and its load is spring supported directly from theside frames, through the said anti-friction bearings, with freedom forthe truck bolster and body bolster to .move laterally together and toswivebor move anlarly in respect to each other on said'side caringrollers, substantially as described.

3. In a car truck, the combination with side frames having bolstersupporting s rings thereon, of a truck bolster and latera 1noola-tes forthe same, the lowermembers of w ich plates have depending legs whichstraddle the side frames and rest on the bolster s ring caps and aresupported with Jfreedomor vertical motion but held against any lateralmotion or forward and backward motion, in respect to said frames,substantially as described.

In a car truck, the combination with the cast steel, girder-type sideframes havi the bolster sprinrsup )orting brackets cast. integraltherewith an )rojecting from the opposite sides thereof, t e 'springsmounted t ereon in two equal sets on opposite sides of tho vertical websof said frame castings, the truck Abolster and the lateral motionrollers and bearing plates, the lower mems of said bearing plates havingdepending hich rest on the spring caps and stradthe top girders of saidside frames. and

ing lugs embracing' the legs of said plates which side frames areprovided with rslainand cooperating with the top girders of said.Jframes to hold the said plates with freedom for vertical motion .butagainst any lateral motion or forward and backward motion, substantiallyas described.

5. ln-a car truck, the combination with a uniting said bolster with saidlower 'bearing plates with freedom for lateral .motion of the bolsterbut preventing the separation of the u per and lower bearin? plates farenoug for the escape'of the rol ers, substantially as described.

Gf In a car truck, the combination with cas't steel side frames, of thegirder-type,
